Disconnect the plug from
the power source before
making any assembly, adjustments or
changing accessories. Such preventive
safety measures reduce the risk of starting
the tool accidentally. Make certain that the
collet nut is securely tightened before turning
the tool on.
REMOVING
AND INSTALLING
THE
DEPTH GUIDE
ASSEMBLY
The depth guide assembly
consists
of the
depth guide, locking screw and bracket.
In order to remove the depth guide from the
tool, release the locking lever and pull the
entire assembly
straight off of the tool.
To
reattach
the assembly,
fully replace the guide
onto the tool collar and lock the clamp lever
(Fig. 1).
INSTALLING
BITS
(Keyless
models)
The bits are held by a keyless collet system
designed
specifically
for cut-out
bits with 1/8"
(.125"), 1/4" (.250") or 5/32" (.156") shanks.
The bit flutes are sharp and
should
be handled with
caution.
Depress
and hold the shaft-lock
in and rotate
the keyless
chuck and shaft until the shaft-
lock engages
and holds the shaft.
To prevent
damage
to tool.
Never use the shaft lock as a
braking devise to stop the tool from rotating.
Rotate the keyless
chuck (counter-clockwise)
(Fig. 3). Remove the old bit (if there is one)
insert the new bit as far in as possible,
but
not so far that the bit flutes engage the jaws
of the chuck (leave approximately
1/8" of
shank exposed)
Re-engage
the shaft-lock
and securely
tighten the keyless
chuck
(clockwise)
by hand.
Note: When using 1/4" & 5/32" bits it may be
necessary
to use a wrench
on the front of the
keyless chuck to securely
tighten the bit.
